This is the ideal book, playmat and sit-in toy for all toddlers. By using the Convertible as a big book, grown-up and child can read the story together. The Convertible quickly unfolds into a long playmat on which children can use their own toys, or pretend to follow the route of an imaginary or toy fire engine. Then the boards can simply be refolded into a large and sturdy sit-in toy car, complete with windscreen and opening door.
